Indeed. Being the universal and ubiquitous real world phenomena, events 
deserve a full scale discussion. Events as happenings, occurrences and 
occasions are the most familiar things, as being everywhere and every time 
to everything. They are key elements in the very Nature, from subatomic to 
cosmic scale, as well as in life, mental life, social life, in technology 
and industry, mass media and computing, particularly. Natural events, 
physical events, chemical events, biological events, mental events, social 
events, political events, cultural events are just some types of generic 
Event.

Imo, most confusion could be avoided with its adequate defining as "a change 
happening at a given place/time, followed and caused by some other events 
(changes, acts, or actions)."

I am inclined to think that the current downgrading of event as a real world 
"nonevent" comes from its poor ontological study.

Azamat,

There are some events that are easily detected. It is not hard
to tell when a firecracker has exploded. It is much harder to
find the bottom of a recession. It's all in the classifiers
or filters.

An interesting question might be: how do we migrate from detecting
simple events to more complex ones. Or, we might discuss how those
events are represented in an ontology so that they are anticipated
and detected correctly. I am particularly interested in the linkage
between predicates and the metrics for detection.

I just finished G.Lakoff's book on category theory, it is popular
writing but quite an interesting read, "Women, Fire and Dangerous
Things".
